When I first saw this, I did think that this was going to be a re-hash of the Eberron Warforged but made for Pathfinder. I must say that I was gladly surprised and that I was wrong. I liked the Ironborn pdf. I don't really know much about Questhaven being that this was my first pdf that I bought from Rite Publishing, but I decided to include the Ironborn as a race in future Pathfinder game that I am running. I liked the Constructed sorcerer bloodline, and the different traits that Ironborn get to choose from. I do think the Centurion trait might be a little overpowered (it allows the PC to start with Armor equal to plate mail), but I felt the others were interesting and brought background flavor to the Player Character. I think the Ironborn pdf is affordable and a great product.
